Limitations

The NRF24L01+ protocol decoder is missing 0/1 byte CRC and fixed length packages. Both should be trivial to implement, please open an issue if you need that capability.

The BTLE protocol decoder currently supports only advertisement packets on channel 38 and not data packets / frequency hopping. I am still evaluating whether the rtl-sdr hardware is fast enough to track the frequency hopping.

Troubleshooting

Biggest problem is noise, avoid rf auto gain and set as low as possible. I usually get best results with 0-10 db gain.

Second biggest problem is frequency drift. Use kalibrate for a good base line then fine tune the frequency in 50Khz steps until perfect
